Question

Adults store energy within the amnion until reproduction. Permeable. moist skin facilitates cutaneous respiration. Embryos develop within four extra-embryonic membranes QUESTION 7 Which of the following traits make sauropsid avían respiratory systems more efficient than most synapsid respiratory systems? O Air sacs that have extensive capillary network to maximize diffusive rate Unidirectional air fiow enables countercurrent gas exchange Trachea that have longitudinal folds to decrease dead space A muscular diaphragm that allows for faster ventilation rates QUESTION 8 al

Explanation / Answer

The saurospid avian respiratory system is found in birds and it is more efficient system in terms of its unidirectional gaseous exchange properties that is varied from synapsid respiratory system that is found in mammals.

The unidirectional exchange of gases is due to the structure of their parabronchial system which is having smaller lungs passages. So the air capillaries present in parabronchial system get much higher surface area as compared to synapsid respiratory system. Due to this higher surface area more amount of oxygen and carbon dioxide can pass through blood and tissues, which makes   breathing efficient.
